Abstract: A container for retrievably storing substances and retaining temperatures of the substances comprises a container body comprising a neck portion and a body portion, and a container cover comprising cover openings. The body portion comprises interior walls and an exterior wall disposed around the interior walls. The interior walls form chambers within the body portion. The neck portion comprises openings in a base wall of the neck portion. The openings lead into the chambers. Each of the interior walls is thermally isolated from the interior walls and the exterior wall. The interior walls and the exterior wall thermally isolate a substance for retaining a temperature of the substance stored in each of the chambers. The cover openings couple with the openings based on coupling the container cover with the neck portion. The container cover allows an independent retrieval of the substances from the chambers through the cover openings.

Abstract: Disclosed is a drone configured for multiple uses. The drone may include a body and a sensor configured to be attached to the body. Further, the drone may include a plurality of arms configured to be attached to the body. Further, a first end of an arm of the plurality of arms may be attached to the body at a first movable joint. Further, the arm may include a first part connected to the first movable joint. Further, the arm may include a second part attached to the first part at a second movable joint. Further, the arm may include a powered rotor including a shaft configured to provide rotatory motion. Further, the powered rotor may be attached to one or more of the first part and the second part. Further, the drone may include a plurality of propeller blades attached to the shaft.
